Their first patient, Kathy Sanford, received the implants last October. Prior to the surgery Sanford had been diagnosed with mild Alzheimer’s, and her symptoms were progressively getting worse. But after five months of continuous stimulation from the brain pacemaker her performance on cognitive tests have vastly improved."
